Retransmission Concept

The Oracle-recommended IP network environment for signaling traffic has:

• RTTs set according to traffic (see Refine RTO Parameter)
• Minimal errors (< 0.01%)
• Minimal jitter

A transport protocol provides transport reliability through two mechanisms:

1. Explicit Data Acknowledgements: the sending side retains transmitted data until the receiving side explicitly acknowledges its receipt
2. Retransmission Timer: the sending side maintains a timer, and if the timer expires prior to receiving an acknowledgement for the transmitted data, then the sender will “retransmit” the data to the receive end
